這是ANSI H35.1的解釋，國內(nèi)大多沿襲該標(biāo)準(zhǔn)。我翻譯了一點(diǎn)，但是我覺得還是看原文對(duì)理解有幫助！The first digit following the H indicates the specific combination of basic operations, as follows:H后邊第一個(gè)數(shù)字表明基體中的特殊化合物，如下：H1 strain-hardened only. Applies to products that are strain-hardened to obtain the desired strength without supplementary thermal treatment. The number following this designation indicates the degree of strain-hardening.H1 應(yīng)變硬化 指經(jīng)過僅應(yīng)變硬化無其他附帶熱處理獲得設(shè)計(jì)強(qiáng)度的產(chǎn)品狀態(tài)。該符號(hào)后續(xù)的數(shù)字表示應(yīng)變硬化的程度。H2 strain-hardened and partially annealed. Applies to products that are strain-hardened more than the desired final amount and then reduced in strength to the desired level by partial annealing. For alloys that age-soften at room temperature, the H2 tempers have the same minimum ultimate tensile strength as the corresponding H3 tempers. For other alloys, the H2 tempers have the same minimum ultimate tensile strength as the corresponding H1 tempers and slightly higher elongation. The number following this designation indicates the degree of strain-hardening remaining after the product has been partially annealed.H2 應(yīng)變硬化加不完全回火 指經(jīng)過應(yīng)變硬化后再經(jīng)不完全回火調(diào)整降低強(qiáng)度以得到設(shè)計(jì)強(qiáng)度的產(chǎn)品狀態(tài)。對(duì)于室溫下柔性合金，H2狀態(tài)有與H3狀態(tài)相同的極限抗拉強(qiáng)度。對(duì)于其他合金，H2狀態(tài)有與H1狀態(tài)相同的極限抗拉強(qiáng)度和稍高的延伸率。該符號(hào)后續(xù)的數(shù)字表示經(jīng)過不完全回火后的應(yīng)變硬化程度。
